Matlab running only as superuser [SOLVED]

Daedalus24 · 2017-10-19 09:02:25

I have installed Matlab R2017a. If I run

 sudo /usr/local/MATLAB/R2017a/bin/matlab

It works like a charm. If I try to launch Matlab as a normal user it returns this error message

 /usr/local/MATLAB/R2017a/bin/matlab
---------------------------------------------------------------------------
Warning: Cannot locate Java Runtime Environment (JRE) . . .
 
         1. Either a correct JRE was not available for redistribution when
            this release was shipped, in which case you should refer to the
            Release Notes for additional information about how to get it.
 
         2. Or you have tried to use the MATLAB_JAVA environment variable
            to specify an alternate JRE, but MATLAB cannot find it.  Please
            run 'matlab -n' to determine what value you are using for
            MATLAB_JAVA and fix accordingly.

Both java 9 and java 8 are installed on my system. Can you please give me a hint?
Thank you!

What's the output of...

archlinux-java status

Daedalus24 · 2017-10-19 11:07:16

The output is:

Available Java environments:
  java-8-openjdk
  java-9-openjdk (default)

It's really intriguing.

Did you try running matlab -n?

Daedalus24 · 2017-10-20 06:35:27

Yes I did.

The result is

If running Matlab as superuser, the outcome is

Firstly please stop running matlab as root, and remedy yourself of whatever thought process convinced you that, if things fail to run as your unprivileged user, running them as root is a "good idea". This is exactly the sort of mentality that causes so many problems for users of certain other operating systems which shall remain nameless.

Create a new unprivileged user with default configs and see if they can run matlab. If they can, then there is a problem with your user's configuration files (most likely shell configs).

Thank you for the replies and help. I created a new, unprivileged user, and nothing changed. I also installed Matlab on a laptop and it works there. I will delve into it and compare the two configurations.

Have you tried running it from a bash shell? Why is the LD path different in the two cases?
